Opera is a worthy contender in the browser wars, mostly for speed. But I'm afraid the world doesn't need another browser. Chrome is also focused on speed, and will win simply from Google's marketing power. Firefox beats in on plugins, etc.

It's a shame really because Opera was clearly designed by some brilliant people. And indeed they were the first to introduce some features (like mouse gestures) that were quickly adopted by other browsers. They deserve a lot of credit for that. But it basically goes to show you that you can't be just a little bit better in UI to gain market share. IE, despite a VASTLY inferior interface still retains to most market share for browsers. While Opera is commendable, Firefox and Chrome have a much better chance of taking that spot from IE.
